Signature Moves

• Reference lock through mathematics pressure.
• Coalition pivot through mathematics pressure.
• Long-game attrition through mathematics pressure.

Timeline

• Modern: Katherine Johnson enters the record through mathematics leverage.
• Peak pressure: Trajectory Analyst status stabilizes across north america memory systems.
• Long aftershock: debates about mathematics and navigation remain active in later eras.

Major Actions

• 1. Katherine Johnson: Changed the operating assumptions of communication, industry, or computation.
• 2. Katherine Johnson: Made an abstract system usable enough to alter later infrastructure.
• 3. Katherine Johnson: Left a framework that later builders expanded, standardized, or contested.

Controversies

• 1. Katherine Johnson: Credit disputes often widen once collaborators, financiers, and institutions are considered.
• 2. Katherine Johnson: The inventor myth can hide supply chains, labor, and the politics of adoption.
• 3. Katherine Johnson: Transformative systems may produce benefits and downstream harms on very different timelines.

Card Notes

• Primary pressure vector: scholarship and diplomacy.
• Representation policy remains portrait allowed.
• This card record is seeded as a concise prototype entry and expects future source expansion.
